I have a small sample of the new RGB "Companion" 3.0 Boards that are available
I will also update the classic design with the new features of the RGB Board and offer that one as well.
The original NES Power Module from the 80's is very noisy. The Power Traces cross eachother and the ground home path is messy. EMI was not a worry in 1985 but noise can impact picture and sound quality

Goals with these new NES Power Modules
- Full Ground Plane that is uninterrupted and is free of traces and components.
- Power Traces that do not cross and have the GND plane below for a good return power signal.
- Have a specific NES Power Module for each use case (not try and pile everything into one board)
NES Classic USB C Powered Module
USB C Powered - NESRGB Companion Power Module with YPbPr "Component" Video
NES Classic with Composite Out and Two Channel Mono Sound.
NES RGB with Genesis 2 9 Pin Output
Full uninterrupted ground plane on the back of the board.
An easy to solder DIY Version of the Classic Composite RCA Edition.
For the few that own the NES HDMI Board, this module will provide very easy solder points without the need of the LDO.
Below is an example of the Orignal Power Module. Notice how the power traces keep crossing eachother and other components. Folks really didn't consider EMI a lot back then and opted to just cover the entire board in a metal shroud.
